Discover the Azure Cosmos DB change feed - Episode 5 (Azure Cosmos DB Live TV)

Mark Brown is joined by program manager Tim Sander to go deep on one of the coolest features in Azure Cosmos DB, change feed. Change feed is a persistent record of changes to a container. It listens to an Azure Cosmos container for any changes and then outputs the sorted list of documents that were changed, in the order in which they were modified. Change feed can be used to move data, trigger events, or stream data.
